1 Claim.

This invention is a fluid collector for smoking pipes, and is specially directed to the means for collecting the fluids distilled from tobacco during smoking, and which fluids are normally col lected within the stem of the pipe and frequently drawn into the mouth. As these fluids contain injurious substances, being actually poisonous, and in addition thereto, having a very disagreeable taste and odor, it is desirable to provide means whereby these fluids may be prevented from entering the mouth, and readily disposed of.

It is known that pipes have been made with various devices intended to collect these fluids, but in all cases these devices have been impractical, inoperative, or formed in such manner that they were ineffective due to the difficulty in cleaning and removing the fluids. One type is of the curved stem variety in which an auxiliary pocket is formed in which the fluids are to be collected, but this pocket is in such a position that it is almost impossible to clean and soon becomes plugged with gums and fluids which give an extremely bad odor to the pipe and after this condition exists, the cup or chamber is ineffective.

The present invention overcomes all these undesirable features and is readily kept clean, and has no tendency to clog up, and with suitable care, no possibility of drawing any of the fluids into the mouth.

The main object of the invention therefore, is to provide an efficient and practical means of collecting the fluids created by the smoking of tobacco in the pipe.

Another object of the invention is to provide r a means as outlined which is readily cleaned and removed, the parts affecting the method being readily accesssible and easily cleaned.

A further object of the invention is to provide a replaceable absorbent element for absorbing the liquids, and which element is easily removed 40 and replaced.

Other objects and advantages of the invention will become apparent as the following description is read on the drawing forming a part of this specification and in which similar reference 45 characters are used to designate similar parts throughout the several views, of which:

Fig. 1 is a plan view of my improved pipe.

Fig. 2 is a longitudinal sectional elevation through the invention.

Fig. 3 is an enlarged fragmentary sectional view through the fluid collecting chamber and the absorbing element.

Fig. 4 is an end view of the absorbing element.

My invention is applicable to pipes of any standard form, and is shown in the drawing as consisting of a straight stem pipe having a bowl EB and a stem i 5, these two parts being of the usual construction and provided with the usual smoke passages l2 and i3.

My invention consits of two coaxial stepped counter-bores it and it formed in the pipe end of the stem H, and communicating with the smoke passage it.

An annular recess is formed on the stem end it of the gowl or pipe proper, which annular recess flts into the counterbore M. A ferrule ll is applied over the pipe end of the stem ES to cover the locking means, which consists of a pin l8, which is fixed in the end of the pipe as indicated, and which cooperates with an L-shaped slot #9 formed in the pipe end of the stem H, and through the wall of the large counterbore. A tube 25 is frictionally secured in the passage 52 and projects into the counterbore it when the pipe and stem are assembled, the tube being out of 9 contact with the walls of the counterbo-res.

An absorbent element 2i of cylindrical form flts within the counterbore M, and has an axial aperture 22 which fits over the tube 29, this element being readily replaceable and adapted to 25 absorb the fluids created by the burning tobacco burnt within the bowl I 6.

It will be noted that by the bayonet locking device that the stem is securely and detachably locked to the pipe proper, and that by removing the stem from the pipe, the absorbing element is easily removed and replaced, as it is merely necessary to slide the element ofi of the tube.

The fluids enter the chamber and are condensed on the walls of the chamber, and flow 35 back into the counterbore M where they are collected in the event that the absorbing element 2! is not used, and in the event that this absorbing element is used, the fluids are absorbed by this absorbing element, which element is periodically discarded or washed.

This absorbing element may be formed of any absorbent material such as cotton or linen, or any other material which will effectively absorb the tobacco fluids.

Having described an operative method of collecting the fluids created by the smoking of tobacco within a pipe, it will be understood that variations in the construction and arrangement of parts which are consistent with the appended claim may be resorted to without detracting from the spirit or scope of the invention or sacrificing any of the advantages thereof. 55

and the stem-engaging portion, a. tubular member projecting from the outer end of the bore of said stem-engaging member into the larger counterbore and in axial alinement with the smaller counterbore, and a cylindrical absorbent member enclosing the exposed portion of said tubular member and filling the space between the tubular member and the wall of the larger counterbore FRANK O.
